BIFOCAL

 

A lens with two fields of vision seperated by a line. Generally the top is designated for distance-vision or computer-distance and the bottom for near-vision work such as reading. 

 

The total lens height for a Bifocal lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but 30mm is the minimum height for a bifocal lens. If the frame chosen has a lens height smaller than 30mm, a different frame must be chosen for Bifocal lenses.

 

In a Bifocal lens, the two fields of vision are specifically differentiated by a visible line. The bottom reading area is 25mm wide and is positioned just below the centerline of the lens. The physical position of the bi-focal area will be affected by the physical height of the lens chosen.

 

 

PROGRESSIVE

 

This refers to the lens design which includes three fields of vision, without lines, and is sometimes referred to as a "no-line bifocal". 

 

The lens height for a progressive lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but the minimum lens height is 30 mm. If this frame has a lens height smaller than 30mm, a different frame must be chosen for progressive lenses.

 

In a progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or a mushroom, with the top portion for distance-vision, narrowing to the lower middle for mid-range, finally to the bottom portion for the near-vision or reading. The reading area is approximately the lower quarter, central third of the lens.

 

It is a good design, without lines, for general use. People sometimes prefer a single-vision lens for extended reading or up-close work.

This refers to the lens design which includes three fields of vision, without lines, and is sometimes referred to as a "no-line bifocal". 

 

The lens height for a progressive lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but the minimum lens height is 30 mm. If this frame has a lens height smaller than 30mm, a different frame must be chosen for progressive lenses.

 

In a progressive lens, the shape of the corrected part of the lens is approximately that of a funnel or a mushroom, with the top portion for distance-vision, narrowing to the lower middle for mid-range, finally to the bottom portion for the near-vision or reading. The reading area is approximately the lower quarter, central third of the lens.

 

It is a good design, without lines, for general use. People sometimes prefer a single-vision lens for extended reading or up-close work.

 

 

 BIFOCAL

 

A lens with two fields of vision seperated by a line. Generally the top is designated for distance-vision or computer-distance and the bottom for near-vision work such as reading. 

 

The total lens height for a Bifocal lens must be 30mm or greater. We recommend a taller lens for more comfortable wear, but 30mm is the minimum height for a bifocal lens. If the frame chosen has a lens height smaller than 30mm, a different frame must be chosen for Bifocal lenses.

 

In a Bifocal lens, the two fields of vision are specifically differentiated by a visible line. The bottom reading area is 25mm wide and is positioned just below the centerline of the lens. The physical position of the bi-focal area will be affected by the physical height of the lens chosen.
